Hey guys, I just bought my first harley a 97, sportster 1200 custom. The bike is in mint shape with 20,000 miles. Has been stored in a basement all winter and started right up. I have put about 300 miles on the bike and love it. I changed the engine oil, primary fluid and installed new spark plugs. My ? is how typical is the cough or carb burp? Runs awsome when u crank on it all through the rev range. When cruising 5th gear 40-45 MPH it gets occasional hiccups. Slow cruising around town it does it also. I know some of this is expected, but how much and how often I wonder. The bike is stock with screaming eagle pipes. Idles good also.

If the baffles are out of the pipes you are going to get that a little bit. From the post I have read on here, it's really nothing to worry about. I had the same thing happening when I bought my 01 883 last year. I have since turned it into stage 1 and all of that went away, and the increase in performance was great. The total cost to stage 1 was about $150.00, well worth it. Hope that is of some help.

I am not sure if the baffles were taken out or not, but the screaming eagle stock pipes are kind of loud, not obnoxious but a nice rumble. I am curious as to how many others have had this or if it is indeed a harley thing. I wouldnt mind putting a few bucks in it to straighten it out though.

Yesterday I spoke with a local tuner who told me has had a lot of sportsters with the same problem and its most likely solved by re-jetting. Stated he uses the dynajet kit and it makes quite an improvement. Kit and labor qouted at $160. This guy has a good reputation with quality work and performance results so I will have him do it. Dam hes busy so I have to wait a week n a half, well least I can still ride it till then. What is actually Stage 1? is that a filter mod too as I have a K&N.

You might want to read around here for a bit before you decide to put a DynoJet kit in it. There are other alternatives.

My 06 also burps, have taken it back to dealer 4 times and was told by the manager at the harley dealer that it was normal for a carb bike and I have a strong running bike, It seems to be less frequent the more I have rode the bike or maybe I have just got used to it, I decided to just leave it alone unless it becomes a real problem for me, the bike runs good, other then occasional hiccup

It sounds like you have not changed any jets. Have you or is your mixture adjustment screw drilled out so you can adjust it? It sounds to me like a small turn out of the adjustment screw would take care of your light throttle farts. I wouldn't jump to changing out the slow jet just yet...
